Answer:

The measure of angle x is [tex]15\°[/tex]

Step-by-step explanation:

we know that

In the figure

[tex]75\°+x\°=90\°[/tex] -----> by complementary angles

so

Solve for x

[tex]x=90\°-75\°=15\°[/tex]

Answer:

The slope of the line would be -2.

Step-by-step explanation:

Because the equation is a line, the slope is the same throughout the entire graph on the equation.

Lets let f(x)=y=-2x+4.

f(0) = -2(0) + 4 = 4

f(0)=4

f(1) = -2(1) + 4 = 2

f(1)=2

Use the equation to find slope.

m(slope) = [tex]\frac{2-4}{1-0}[/tex] = [tex]\frac{-2}{1}[/tex] = -2

The slope would be -2.

Or:

Use the equation y = mx + b where m=slope.

In the equation y=-2x+4, m=-2.

The slope is -2.

Answer:

y = -2x + 4 slope is -2

To find the interquartile range take the third quartile (the right line of the box) and subtract the first quartile (the left line of the box)

33-25 = 8

Answer:

D

Step-by-step explanation:

The opposite angles of the inscribed quadrilateral are supplementary

∠A + ∠C = 180 and ∠B + ∠D = 180

∠B + ∠D = 93 + x + 30 = x + 123, hence

x + 123 = 180 ( subtract 123 from both sides )

x = 57 → D

Answer:

The correct answer is B) (x + 4)(x - 4)

Step-by-step explanation:

We can tell this since it crosses the x axis at 4 and -4. This means we need parenthesis that gives us these two values.

The sequence given is a geometric sequence with a common ratio of -3. The sum of the first ten terms of the sequence is calculated using the formula for the sum of a geometric series to be -236196.

The sequence given, 4, -12, 36, -144, ..., is actually a geometric sequence. In a geometric sequence, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. In this sequence, the common ratio is -3.

To find the sum of the first n terms in a geometric sequence, we use the formula: S_n = a(1 - r^n) / (1 - r), where S_n is the sum of the first n terms, a is the first term in the sequence, r is the common ratio, and n is the number of terms.

If we insert our values into formula, we get: S_10 = 4*(1 - (-3)^10) / (1 - (-3)), which results in S_10 = -236196.

So, the sum of the first ten terms of the sequence is -236196.

x(roots)  = 3, 1, -4.

Step-by-step explanation:

Find the roots by solving for x.

Hope this helps,

Davinia.

x^3 - 7x = 6x -12

Subtract 6x from both sides:

x^3 - 13x = -12

Add 12 to both sides:

x^3 - 13x +12 = 0

Factor the left side:

(x-3) (x-1)(x+4) = 0

Now solve for x in each set of parenthesis so they all equal 0:

x = 3

x = 1

x = -4

The roots are 3,1, -4

Answer:

A fraction that would be equivalent to 3/6 would be 1/2, therefore a shaded circle would be half of a circle.

Step-by-step explanation:

Look at the picture.

Divide the circle to six congruent pieces. Shade three pieces.

Equivelent fractions:

[tex]\dfrac{3}{6}=\dfrac{3:3}{6:3}=\dfrac{1}{2}\\\\\dfrac{3}{6}=\dfrac{3\cdot2}{6\cdot2}=\dfrac{6}{12}\\\\\dfrac{3}{6}=\dfrac{1}{2}=\dfrac{1\cdot2}{2\cdot2}=\dfrac{2}{4}\\\vdots[/tex]

A regular hexagon have an interior angle of 120°, while a regular decagon have an interior angle of 144°.

The regular hexagon will tessellate because 3 hexagons can be tessellated at a point. (360° / 120° = 3)

The regular decagon will not tessellate because 360° is not divisible by 144°.

Answer:

Your answer is incorrect. Correct answer is f(-8) = -3

Step-by-step explanation:

[tex]f(x)=\dfrac{x+2}{2}\\\\f(-8)\to\text{put x = -8 to the equation of the function}\ f:\\\\f(-8)=\dfrac{-8+2}{2}=\dfrac{-6}{2}=-3[/tex]

The value of f(-8) refers to the result of a function, f(x), when x equals -8. However, without the specific function, we cannot provide an exact value.

To determine the value of f(-8), we need to know the function f(x). In mathematics, f(-8) typically refers to the value of a function, denoted as f(x), at x=-8. For instance, if we have the function f(x) = x^2, then f(-8) would equal to (-8)^2, which is 64. However, without knowing the specific equation for f(x), we cannot provide the exact answer for f(-8).

Step-by-step explanation: got it righ

Ok, so first, the y-intercept is always the last number. So the y-intercept for the first equation would be -1, and for the second equation, 4.

Put a dot, or a point on -1and 4 on the graph.

The slope is always he number with an x.

So the slope would be 3 for the first equation.

And the slope for the 2nd equation would be -2.

If the slope doesn't have a denominator, put 1 as it's denominator.

So, 3x would turn into

[tex] \frac{3x}{1} [/tex]

And -2x would turn into

[tex] \frac{ - 2x}{1} [/tex]

So the rule for slope is:

[tex] \frac{rise}{run} [/tex]

So, go to your -1, and go up 3 and 1 right. Keep doing that until you reach the end of the graph.

Now, go to your -4, go down 2 and go left 1. Keep doing that until you reach the end of the graph.

Now, draw the lines.
